A use-after-free flaw in Windows Hyper-V lets an already authorized attacker raise privileges. The attacker must act locally with high privileges; no user interaction is required, and the issue is hard to exploit. A successful attack can fully compromise confidentiality, integrity, and availability beyond the vulnerable component. Microsoft has not listed affected builds.
What to do: Apply Microsoft's update for CVE-2026-113861. Microsoft has not listed a fixed version or workaround.
